What must be true about the coordinates of any point that lies in the third quadrant?
Both coordinates are negative in this case.
What is true of the y-coordinates below the x-axis?
They have negative values
Is it true that polar bears can run 25 miles an hour and jump opver 6 feet in the air?
No it is not true
How do you find a point lying on the line?
Substitute the coordinates of the point into the equation of the line. If the result is true, then the point is on the line.
How do you calculate total percentage error?
It is 100*(Calculated Value - True Value)/True Value
True or False: The polar coordinates of a point are unique?
False
True or False: One advantage of polar equations is that you can use a polar function to describe a graph whose equation in rectangular coordinates would not be considered a function?
True
True or False; The value r represents the reference angle when plotting a point in polar coordinates?
False
Do rectangular coordinates have the same property as polar coordinates?
Some of them but not all. For example, uniqueness. The rectangular coordinates (x, y) represent a different point if either x or y is changed. This is also true for polar coordinate (r, a) but only if r > 0. For r = 0 the coordinates represent the same point, whatever a is. Thus (x, y) has a 1-to-1 mapping onto the plane but the polar coordinates don't.
true or false the value of theta represents the distance from a point to the pole when plotting a point in polar coordinates?
False
How do you calculate the GDT true position of a given feature?
Square root of x + y divided by 2
True or False. The rectangular coordinates of a point are unique?
True
What must be true about the coordinates of any point that lies in the third quadrant?
Both coordinates are negative in this case.
What is true about all coordinate points in quadrant IV of a coordinate graph?
Their first coordinates are positive and their second coordinates are negative.
Molecule that contain polar bond are always polar molecule?
Yes, it is true.
What is true about a molecule which contains two polar bonds which have the different degrees of polarity will it always be polar or never be polar or only be polar if it is bent?
A molecule with two polar bonds of different polarities can still be polar if the individual bond dipoles do not cancel each other out. The overall polarity of the molecule depends on its geometry and symmetry. If the molecule is linear, it will not be polar regardless of the differing bond polarities. If it is bent or asymmetrical, it will be polar.
Is the following sentence true or false water molecules are polar?
True
